Abstract:
The study was aimed to analyze Del phenotype of RhD (-) unrelated blood donors. RhD (-) was initially screened by routine serological test and confirmed by indirect antiglobulin test (IAT). Del phenotype was detected by hot-ether absorption-elution test. The results indicated that 106 RhD (-) samples were confirmed out of 38526 donors, and 28 cases were Del detected by hot-ether absorption-elution test. The incidence of Del in RhD (-) samples was 26.41%, The serological phenotypes of Del were Ccee (78.57%), CCee (14.29%) and CcEe (7.14%) respectively. In conclusion, the detection of Del by using hot-ether absorption-elution test is very important for reasonable application of RhD (-) blood. There is difference in Del phenotypes of populations in different regions of China and Japan.
